Embodiment
With reference to figure 6 are flow chart of steps of the inventive method, and the inventive method comprises:
Step 601, connect a plurality of physical site with communication medium and form binding base stations, and described physical site is configured to one respectively has the physics main website of unique address sign and the physics slave station that one or more address interconnect is not conflicted, with described physics main website as master node, with described physics slave station as slave node or isolated node;
Step 602, each node are set to relatively independent, and each node is independently controlled Operation and Maintenance and the service channel that starts flow process, independent maintenance access network side, safeguard the aerial side business channel control flow of being correlated with separately;
Step 603, master node only are responsible for the relevant and additional thus necessary flow tasks of control channel, and other function of base station is independently born by each node.
The present invention is mainly the method for supporting to set up automatically mode of binding communication in base station in a kind of topological communication network that connects, and main feature is:
1) principal and subordinate's attribute of base station is determined by the connector of binding media (such as the binding cable);
2) solve the implementation of multi base station binding operation function, realize two base stations and surpass the binding of two base stations (three base stations, four base stations etc.);
3) support binding operation under the multiple integrated mode in base station, except can provide realized in the practical application one main one from bundle feature, can realize that in addition one is main many from, the mode of main many independent operations, slave station and an independent operation base station hybrid working;
4) binding base station electrifying startup order is unrestricted.And the binding base station communication network is realized adjusting automatically in the various schemes that These characteristics 2 comprises according to the variation Automatic Optimal of actual conditions.For example during main station failure, all slave stations of binding base station automatically switch to the stand-alone base station mode and work, thereby the risk of multiple base stations united operation is reduced to minimum.
1, characteristics of the present invention are, support that one is main many from, main many independent operations, slave station and an independent operation base station blend modes of operation.
The inventive method is supported multiple binding mode of operation, be applicable to that a plurality of slave stations of main website normally bundle situation, perhaps bundling unsuccessful situation is a plurality of independent operations base station mode of operation, also be applicable to half binding success status, promptly have successful slave station and the independent operation base station of binding in the physics slave station simultaneously with main website.Support that multi-operation mode offers convenience to the network optimization, the attendant determines whether to adopt the binding scheme with reference to the service feature data.
2, equipment of the present invention comprises:
The main website of unique address sign in the binding base station;
Be configured to the physics slave station that address interconnect is not conflicted;
The communication medium that connects master node and physics slave node, this communication medium are such as cable, and the port that is connected with node provides the numeric address of not conflicting mutually configuration.
For realizing binding, the soft hardware equipment of each base-station node is identical, and each node has driver and the acceptor device that is used for information receiving and transmitting in the binding communication network.Need not to download special parameter configuration from webmaster, need not to download special software version to main website, also need not to be provided with hardware switch such as wire jumper and select, only determine automatically that by the port that connects medium of communication the binding physical attribute of node is physics main website or physics slave station at node.Concerning the user, no matter whether this node bundlees, the binding attribute how, sees that from the webmaster side each base station all is an independently base station unit.The base station does not bundle memory function yet, otherwise needs special configuration as non-binding base station use or before readjusting the main and subordinate node position.
In the present invention, each node is relatively independent in the binding communication network, and promptly the base station is independently controlled and started flow process, and the Operation and Maintenance and the service channel of independent maintenance access network side are safeguarded the aerial side business channel control flow of being correlated with separately.
Design characteristic is each node control of binding base station and the relative transparent independence of management like this, and main website only is responsible for the relevant and additional thus necessary flow tasks of control channel, and other function of base station is independently born by each node.But not design the master control management node that a function is concentrated, avoided in the binding communication network binding control messages frequent between main controlled node and child node mutual.
The further characteristics of above-mentioned execution mode are to comprise a kind of main website, the relevant control flow with control channel of main website tissue, the management of slave station and own resource validity under the responsible binding base station.When the terminal traffic application is received by main website, select the effective service node according to mapping table.Comprise a kind of slave station, slave station sends binding attribute change and the operation state change message of self in real time to main website, and receives the terminal traffic assignment request that the processing main website issues at normal operation state.
The main website of logic base station is responsible for the control of CCH related procedure, so main website sets up and safeguard all physics slave stations binding attribute and operation state mapping table.This table needs real-time update, determines the binding attribute of corresponding node by the startup request of physics slave station transmission; The current operation state of in real time synchronous slave station when the binding attribute change notice of slave station is received by main website, is removed the original information of node, rebulids Binding information; When main website detects between the principal and subordinate communication link and interrupts, be responsible for removing the binding attribute and the operation state information of corresponding slave node.Only when this node binding attribute be slave station, and its operation state is when putting into effect, the resource that this node is looked by main website is effective.
Here point out that the independent operation base station is meant that node is the physics slave station, but working method is with non-binding base station, one of them channel is as control channel.Main website and a plurality of slave station are formed a binding communication net among the present invention.
3, another characteristics of embodiment of the present invention are, binding base station is supported the non-order random start of single node, and each physical node determines to bundle separately attribute in start-up course.
These characteristics of this method show can guard binding base station electrifying startup order rigidly, offers convenience to Operation and Maintenance.Physics sends the startup request message to main website from stand in start-up course, main website is according to the current starting state of parameter information and main website of physics slave station, and indication physics slave station is worked in the mode of slave station or independent operation base station, and sets up the Binding information of corresponding node.If having precedence over main website, the physics slave station starts, and work in the independent operation mode, the physics slave station detects the binding communication link establishment with main website after main website starts, owing to do not receive the physics slave station binding attribute indication that main website sends before finding, allow to restart, start request message to send to main website.
4, another characteristics of embodiment of the present invention are, support single node and groups of nodes to change the binding attribute automatically in binding base station startup and operation process, realize that the tie-in mode Automatic Optimal is switched under the abnormal conditions.
These characteristics of this method show that owing to have only main website to send CCH under the binding base station normal condition, the channel resource high usage has also brought high failure risk: main station failure might cause whole binding communication network not work; Because environment reason, hardware fault, base station edition mistake etc. also may cause slave station binding failure.This design allows the binding communication network to seek the optimal working mode in all cases automatically.
Main station failure is handled main website and is allowed the binding attribute of physics slave node in the communication process dynamically to switch between slave station and independent operation base station.When main website breaks down, according to physics slave station binding attribute list, notify all slave stations to change independent operation base station mode into and work, this binding base station is runed with many independent operations base station mode.When main station failure recovered to put into effect again, the physics slave station that allows to satisfy the binding condition sent the startup request message to main website again, changes the binding mode of operation.
The further characteristics of above-mentioned execution mode are, slave station can't be realized normal binding and when changing the independent operation base station into, can directly notify main website binding attribute to change in start-up course or the operation process.When these characteristics also allow the physics slave station can't normally bundle owing to reasons such as clock synchronization mistake, link communicating interrupt, change independent operation base station operate as normal into, need the binding attribute list of notice main website with the management of synchronous main website.
The further characteristics of above-mentioned execution mode are, the parameter configuration change of independent operation base station, and when satisfying the binding communication condition, this physics slave node sends to main website again and starts request message, changes the slave station mode into and works.
The parameter, version information and the communication link state that reconfigure node as the user just often, the pattern of binding base station is adjusted again automatically, allows the node binding of independent operation.
5, another characteristics of embodiment of the present invention are, the monitoring process between binding base station main website and the physics slave station, periodically regularly mutual binding attribute, operation state information.The binding abnormality detection belongs to low priority task, under the situation that guarantees principal and subordinate base station regular traffic communication function bandwidth, realizes principal and subordinate base station operation state and bundle the attribute list abnormality detection handling.
6, the State Control strategy of the binding base station of embodiment of the present invention comprises:
Main website is responsible for the operation state control of self and all slave stations;
The operation state of slave station is limited by main website;
The operation state variation of independent operation base station is independent of main website.
Change order at the operation state of main website and be issued to all slave stations simultaneously, except the order that puts into effect, issue the slave station order that puts into effect after main website puts into effect.State Control order at main website is not issued to all independent operation base stations.State Control order at slave station is only effective to self, but before slave station puts into effect, needs to send putting into effect request to main website, waits for that main website puts into effect to allow order or forbid indicating, and promptly has only just to allow slave station to put into effect in the main website operation.State Control order at the independent operation base station is only effective to self, and is irrelevant with other node.
Above-mentioned explanation shows that each node of communication network that success bundlees is as a base station overall work.Have only just to allow slave station to put into effect after main website puts into effect, the state variation that main website withdraws from operation, restart must have influence on all slave stations.Can do local the adjustment to the binding communication net again simultaneously, allowing separately, certain slave station of control withdraws from operation, restarts.
Below illustrate further combined with accompanying drawing.
Fig. 1 uses a kind of binding base station topology of personal wireless communications system diagram of communications networks that the present invention has realized.The bus-type topological network that adopts RS-485 to connect, each endpoint configurations of bus become unique numeric address (00h～03h).Adopt differential driving half-duplex connected mode, the A among the figure is connected to the data signal line signal, and B is connected to the clock line signal, and the 5ms clock of clock line output main website is as the synchronisation source of slave station 5ms.Network normally moves and allows to insert 1～4 node, is the bus port of 00h if the base station connects physical address, and this node just becomes main website, and all the other nodes that this method regulation is connected on the bus are the physics slave station.The communication protocol that is applied in the RS-485 network is selected to have a lot, and master/slave agreement is used in master/slave agreement, token transmission and collision detection etc. in this communication network, adopt the mode of main website poll physics slave station.
Fig. 2 and Fig. 3 are that main website and the physics slave station that the present invention realizes starts flow state machine figure, these two symbolic significances of simplifying state machine diagram are identical: symbol M x and Sx represent the state of main website and physics slave station respectively, symbol? mx/? mxx represents to receive message, symbol! Mxx represents to send message, and x/xx is a numeral, and solid line is represented the message in the binding communication network, the message in the dotted line representation node, and the direction of arrow is represented the migration of state machine.
Main website has only two states: move to the Mb attitude by initial state Ma after finishing initialization, main website receives and handles the message that the physics slave station sends at the Mb state.The physics slave station has three-state: Sa is an initial state, and Sb is a slave station mode, and Sc is the independent operation pattern.Each message implication is described as follows among Fig. 2 and Fig. 3:
Symbolic messages title direction
M1 physics slave station initiate notification message host node＜-from node
M2 indication physics slave station is with slave station attribute work host node-from node
M2 ' indication physics slave station is with independent operation base station mode work host node-from node
The failure of m3 link communication abnormality or principal and subordinate's clock synchronization is from node-from node
M4 notice master node binding attribute changes be independent operation base station host node＜-from node
M5 principal and subordinate binding condition is recovered message from node-from node
M6 notice main website remove this node Binding information host node＜-from node
After message m 1 is received by main website, judge whether the parameter of slave station and version information satisfy the binding condition, then send instruction m2, otherwise send instruction m2 ' if satisfy.Provide the successful condition of main and subordinate node binding:
1) the slave station initiate notification message parameter length of receiving is predefined consistent with main website;
2) main and subordinate node version number unanimity;
3) the CCH frequency unanimity of main and subordinate node parameter downloads;
4) operator's unanimity of main and subordinate node, and be in the same call district;
5) main website software and hardware initialization success, no catastrophe failure.
From stand in start-up course, owing to take place that communication link interrupts or main website can't provide the indication or the 5ms clock failure etc. of main website is unusual synchronously of putting into effect for a long time, slave station receives that message m 3 backs send message m 4 to main website, the binding attribute changes of notifying this node is the independent operation base station, and its state is moved to state Sc by state Sb.After the node of giving state Sc was again downloaded parameter or download version, when satisfying above-mentioned binding conditional request, the monitoring program between the principal and subordinate detected this variation, sends instruction m5.The independent operation base station sends message m 6 to main website after receiving m5, the notice main website removes this node Binding information, and binding does not need manually to assign the instruction of reset node again, and node is restarted automatically, again carry out the initial configuration process, and the initiate notification message m 1 of transmission change is to main website.
Fig. 4 is a physics slave station start-up course binding attribute change flow chart, comprising:
Step 410: carry out the software and hardware initialization after the base station powers on;
Step 420: judge the numeric address of binding mouthful, detect for behind the physics slave station by disposing serial port drive from mode;
Step 430: detecting bundle link communication whether normal (LINK OK), is execution in step 440 then, otherwise execution in step 480;
Step 440: send slave station initiate notification message to main website, and the indication of 3 minutes timer wait main websites is set.
Step 450: judging whether to receive main website indication, is execution in step 460 then, otherwise execution in step 480;
Step 460: receiving main website indication, remove timer, judge that the main website indication is to require to run with slave station or in the mode of independent operation base station, is to require with slave station mode execution in step 470 then, is to require with the mode of independent operation base station execution in step 480 then;
Step 470: enter put into effect flow process and process ends in the mode of slave station according to the indication of main website;
Step 480: enter the flow process that puts into effect in the mode of independent operation base station according to the indication of main website.
In addition, when slave station sends initiate notification message, might also the initiate notification of slave station not responded by main website at the software and hardware initialization procedure; Perhaps communication network obstruction etc. causes response message can't arrive from node unusually, then puts into effect according to the independent operation mode earlier from node, wait for main website finish after the initialization or communication normal after, change into the slave station mode and work.
Shown in Figure 5 is that operation operation information flow diagram is normally withdrawed from the binding base station execution.Object is the 1C23T binding base station among the figure, receive that Operation and Maintenance platform (OAM) 510 issues normally withdraw from the operation order before, main website 520 and slave station 522 all be in professional busy in, and the TCH resource of slave station 521 be the free time.The transmission of at first closing self CCH after the message 5010 is received by main website, and broadcasts this message 5020 to all slave stations.Slave station 521 reports operation state change message 5041 to OAM simultaneously because the professional free time is received the message 5031 that withdraws from operation after message 5020 is handled at once to main website 520 transmission slave stations 521.The operation state of revising node slave station 521 after this message, other node current state of not stopping to inquire about base station binding attribute and operation state mapping table are received by main website 520.The TCH resource of main website 520 at first is released among the figure, and at this moment since the operation state of node slave station 522 still in the operation, so the logic base station need wait for that slave station 522 closes all TCH.Last slave station 522 discharges all TCH resources, sends message 5032 and 5042, and main website query mappings table satisfies to withdraw from behind the operation condition to send to OAM and withdraws from operation state change message 5040.This explanation is for normally withdrawing from operation order and do not require that the base station forces to discharge Traffic Channel, and need wait until and just withdraw from operation after the own service resource discharges, and has only after main website and affiliated all slave stations withdraw from operation, and operation is just really withdrawed from the logic base station.Slave station 521 and slave station 522 successively withdraw from operation in the above-mentioned flow process, to Operation and Maintenance process transmit status change message separately.
This shows the binding attribute that is kept in the main website and the importance of operation state mapping table.This table requires the synchronizing information element the least possible for a binding nodal information mapping table of the unique regulation of this method.By one of them characteristic of the present invention: real-time update mapping table under the main and subordinate node Binding information periodic synchronous process, abnormal conditions such as can prevent that internet message from losing.
The above is preferred embodiment of the present invention only, is not to be used for limiting practical range of the present invention; Every according to equivalence variation and modification that the present invention did, all contained by claim of the present invention.

9, method according to claim 8, it is characterized in that, described attribute determining step further comprises: physics sends the startup request message to master node from stand in start-up course, master node is according to the parameter information and the current starting state of master node of this physics slave station, indication physics slave station is worked in the mode of slave node or isolated node, and sets up corresponding node Binding information; If the physics slave station has precedence over the master node startup and works in the independent operation mode of isolated node, then physics detects foundation with the binding communication link of master node from standing-meeting after master node starts, if do not receive the binding attribute indication of the physics slave station that master node sends before, then the physics slave station restarts, thereby send the startup request message to master node, so that this physics slave station changes the mode of operation that operates in slave node into.
10, method according to claim 7 is characterized in that, also comprises supporting single node and the groups of nodes attribute change step that changes the binding attribute, realizes tie-in mode Automatic Optimal switching under the abnormal conditions automatic in binding base station startup and operation process.
11, method according to claim 10 is characterized in that, described attribute changes step and further comprises:
Main station failure is handled: master node allows the binding attribute of physics slave station in the communication process dynamically to switch between slave node and isolated node; If master node breaks down, then notify the mode that all physics slave stations change isolated node into to work according to described mapping table, this binding base station is with the pattern operation of many isolated nodes; If the master node fault recovery also puts into effect again, the physics slave station that then satisfies the binding condition sends to master node again and starts request message, goes back to the mode of operation of slave node;
If slave node can't be realized normal binding and change isolated node in start-up course or the operation process, then directly notify master node binding attribute to change; If when slave node can't normally bundle owing to reasons such as clock synchronization mistake, link communicating interrupt, slave node changed the isolated node operate as normal into, and the notice master node is with synchronous described mapping table;
Satisfy the binding communication condition if be operated in after the parameter configuration of the physics slave station of isolated node pattern is changed, then this physics slave station sends to master node again and starts request message, thereby the mode that changes slave node into is worked;
If the user reconfigures parameter, the version information of physics slave station, and communication link state just often, the pattern of binding base station is adjusted again automatically, allows isolated node to bundle and becomes slave node.
12, method according to claim 7 is characterized in that, also has monitoring process between master node and slave node, in order to periodically regularly to bundle attribute and operation state information alternately; Between master node and slave node, also has the low priority task of belonging to binding abnormality detection, be used under the situation that guarantees master node and slave node regular traffic communication function bandwidth, realize master node and slave node operation state and the processing of binding attribute list abnormality detection.
